sys-firmware/ipxe must be patched so it doesn't use PIE.

build.log? emerge --info? we will not go chasing mailing lists for information.

emerge info

Sorry @Alex

Didn't see anything wrong with linking to an upstream mailing list that described the actual cause of the problem.

Relevant portion of build.log:

But also, from the PIE/SSP bug, #582688:
"Tracker for Packages that fail with pie or ssp enable in Gcc 6.1
The package should block this one _and_ the Gcc 6 porting bug."

[Comment 4 SpanKY 2016-06-21 04:46:16 UTC]

it's not specific to gcc-6.  the code is already patched to disable PIE:
https://git.ipxe.org/ipxe.git/commit/fe61f6de0dd5d39ac3de5e8e18742f9bd0aafad7

the problem is they typo-ed the option -- it's "-no-pie", not "-nopie".

sent fix upstream:
